GAS APPARATUS.

Patented Sept. 11, 1906.

Application filed September 6. 1904. Serial No. 223.397.

To all whom it imt l concern:

Be it known that I, LoUIs ANVAT'rs, a citi zen of the United States, residing at Hartley,

in the county of OBrien and State of Iowa, have invented certain new and useful Improvements in Gas Apparatus, of which. the following is a specification.

My invention relates to improvements in machines for mixing air with gas, and is particularly designed for producing ordinary illuminating-gas.

To this end my invention consists in the features of construction and combination hereinafter particularly described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view ol my improved apparatus. Fig. 2 is a section on line a; 0c of Fig. 1. 3 is an end elevation of a mixing-tank and connected valves, and Fig. 4t is a detail of a portion of the valve mechanism.

In the drawings, A represents a portable tank for holding compressed gas.

B represents an air and gas mixing apparatus, and C represents a storage-tank for holding the mixed air and gas.

bell 40. The water-receptacle of the mixing apparatus is provided with an inner cylindrical partition-wall 4, constituting a central open top chamber within which telescopes a hell or chamber 5, extending downwardly from the outer hell 3.

6 represents a main inlet gas-pipe connected with which is a stand-pipe 7, leading into the chamber 4 to a point above the level of the water 8. The outer end of the pipe 6 is provided with a union 9, by which the pipe is adapted to be connected to the tank A. Arranged in the inlet-pipe 6 adjacent to the stand-pipe 7 is a check-valve 10. From the lower end of the standpipe 7 an outlet gaspipe 11. leads to a pipe 12, which connects with a stand-pipe 13, leading into the storagc-tank O to a point above the level of the water 14 therein. A check-valve 15 is contained in the pipe 11 adjacent to the standpipe 7 In order to fill the air-chamber hell 3, I provide a stand-pipe 16, opening therein at a point above the level of the water, the lower end of the stand-pipe connecting with The mixing ap-{ paratus consists of a water-receptacle 2 and a telescoping bell 3, and the tank O consists oi a water-receptacle 39 and a telescoping an air-inlet pipe 17, provided with an inletcheck valve 18 and connected upon its oppo site side by a pipe 19 with the inlet-pipe 12 of the storage-chamber. A check-valve 20 is arranged in the pipe 19.

In order to control the passage of 001m pressed gas into the mixing apparatus and also the passage of the mixed air and gas from the mixing apparatus to the storagetank, I provide valves 21 and 22 of suitable construction in the inlet and outlet pipes 6 and 11, respectively, of the gas-mixing apparatus. The valves 21 and 22 are connected by a rod 23, the valve 22 being thereby actuated from the valve 21. In Figs. 3 and i is illustrated the actuating mechanism for the valve 21. Having pivotal support 24 below the valve 21 is a triangular lever 25, having a forwardly-extending arm 26, pivotally conpiece being provided upon its inner and outer ends with outwardly-extending studs 33 and v 34, respectively. W'hen the parts are in the position shown in Fig. 3, the cross-piece 32 of the weighted lever stands below the handle 35 of the valve 21.

In operation the storage-tank A being connected with the inlet gas-pipe, as shown in Fig. 2, the gas will be allowed to pass through said pipe by the opening of the valve 36. The gas will pass through the pipe 6 and stand-pipe 7 into the bell 5 of the gasometer, raising the bell. As the bell of the gaso meter is raised a vacuum will be created in the outer chamber and air will be drawn through the pipe 17 and stand-pipe 16 to fill said space. The raising of the bell of the gasometer will turn the valve mechanism, as illustrated in Fig. i, bringing the pin 3-1 of the weighted arm 31 against the handle of the valve 2]. to actuate said handle. The parts are so arranged that this actuating of the handle of the valve 21 will occur when the gasometer becomes filled with gas and air. This closes the valve 21 and by means of the connecting-rod 23 opens the valve 22, allow ing the gas in the gasometer to pass through the pipe 11 to the pipe 12 and the air in the gasometer to pass through the pipe 19 to the pipe 12, in which pipe 12 the gas and air will mix and pass through the stand-pipe 13 into the storage-tank C. From the storage-tank C the mixed gas and air which is now. in the form of illuminating-gas may be drawn off through the pipe 37, the pipe 37 being provided with a suitable valve 38. The lowering of the bell of the gasometer will carry the valve mechanism back to the position shown in Fig. 3, the pin 33 of the weighted lever engaging with. the handle of the valve 21 to open the valve 21 and close the valve 22, when a new supply of compressed gas and air will pass into the gasometer. It will be evident that when the gasometer becomes filled with gas and air it will gradually exhaust into the storage-tank to keep said my improved apparatus the compressed a r and gas is thus automatically fed through long as any gas remains in the tank A.

/Vhile 111 the arrangement shown gas is storage-tank constantly filled. By means of the mixing apparatus to the storage-tank as supplied to the mixing apparatus from a.

tank of compressed gas and delivered from the mixing apparatus to a storage-tank, I

may change the character of gas supplied to the mixing apparatus or deliver it thereto in any other suitable manner and modify the construction and arrangement in other ways without departing from the idea of my invention, the scope of which is defined in the following claims.

Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. An apparatus of the class described consisting of a storage-tank, a gasometer connected therewith consisting of a water-receptacle and a telescoping bell, said belland receptacle being provided with inner and outer chambers, means for separately supplying gas and air to said chambers, controllingvalves arranged in the gas inlet and outlet pipes of said chambers, a connection between said valves, a pivotally-supported trippinglever arranged in connection with one of said valves, and a lever connecting said trippinglever with the bell of the gasometer;

the combination with. a storage-tank, consisting of a water-receptacle and telescoping bell, of a similar gasometer provided with separate chambers, air inlet and outlet pipes for one of, said chambers, gas inlet and outlet pipes for the other chamber, valves arranged in said gas inlet and outlet pipes, a rod connecting said'valves, a handle carried by one of said valves, a lever havingfulcrum-support-adjacent to said handle, and a connection between the outer end of said lever and the bell of the gasometer.

3. In an apparatus of the class described, the combination with a storage-tank consisting of a water-receptacle and telescoping 'bell, of a similar gasometer provided with separate chambers, air inlet and outlet pipes for one of said chambers, gas inlet and outlet pipes for the other chamber, valves arranged in said gas inlet and outlet pipes, a connection between said valves, a triangular lever said valves, a connection between the outer end of said lever and the bell of the gasometer, and an operative connection between the outer and inner ends of said lever and said valve.

In testimony whereof I afiix my signature in presence of two witnesses.
